Hi All,

 Just at the cleanup stage and am thinking around the various exhaust parts to allow re-install on my K.

 I have new studs and nuts and copper washers.
I don't recall seeing any copper washer come out when I removed exhaust all those months ago, so I guess they are still stuck in the ports. Can i just jack 'em out with a flathead or should I be more cautious

Then decided to clean the exhaust and silencer with metal polish ...didn't seem to be getting too far with that idea, so moved to fine wet n dry. Worked a treat, and all those years of grot n grime are slowly coming off and showing a gleaming stainless surface. I'm still amazed at all the little blobs of road tar !!

Just at the finishing stages of rebuild and hope to be back on tarmac soon

adios

Get new rubber mounts for it, don't reuse them.

I always use wet and dry on the headers, works better than anything.

Wish we could get you over to K Fest.

Where the 3 front pipes run fairly parallel put a jubilee clamp around them to stop the vibration induced cracking. Tighten up all the studs a bit at a time, nice and evenly and before you start to get to the stage of crushing the copper washers put the rear mount in position and make all those bolts firm. That way you are keeping the whole system in its natural position.

thanks for replies lads,
 Yes, you might yet Olaf, about 150 days to go and I'll be free to do what I like ( Other 'alf permitting ;-))
Good point re new rubber mounts...hadn't thought of that in particular and I have been thinking of a new rubber gasket for rear drive unit...

On mine it's 4 pipes RickG, and they are all welded in place so no probs there. I'll have a grovel about under it later and see if I can spot any old copper rings in the ports.

Just taking my time and hopefully ensuring all is correct and in the right place, so far so good

The old copper gaskets never fall out in my experience.  I suspect because their diameter increases ever so slightly when they are initially "crushed" upon installation.

I've never bothered to replace them.

+1 on what the Duck said.  I have never replaced those gaskets on any of my bikes and never had a leak there.

I used 2500 wet or dry on my header pipes, made them look nicely polished with minimum expenditures of time and effort. 

Looked the treat...for about 30 miles.

Ok on all that
Am putting 8 new studs in
Plan to use a little thread lock, though I can't imagine they'll fall out. Time will tell i guess

I didn't use threadlock...used copper paste not that tis worth a lot in there.

Oh indeed, i love that copper grease....it goes on everything, except my toast....i reserve that for Kerrygold  ;-)

And i forgot to mention an obvious plus , or at least something that will ease input...the new studs take a hex drive and the new nuts are copper. I'm looking at the old ones, all rusted and nasty,  and thanking a higher being that i got them all out intact & without tooo much trouble

I used stainless studs and nuts with copious amounts of copper anti-seize.  No problem removing them.


Speaking of copper.  Check the "copper" nuts.  The ones I bought from Max BMW were made of some mysterious magnetic copper that quickly rusted.

DeRodster, the copper rings in the K1100rs were invisible to me due to soot. I got a cheap dentists type tool in the € shop and picked them out....turned out there were two sets in there. if you are buying studs make sure they are the right length (They're not the same as 8v ones).

Looking forward to seeing you "out and about".

Copper nuts my eye, unless the laws of physics have changed !



Onwards and upwards, the quest continues ;-)

Of course the laws of physics have changed. This is Ireland after all!

Superglue.....



Can you imagine the fun I had one day when I bought a stainless steel saucepan clearly marked suitable for induction hobs then when I took it home it wouldn't work. Someone in the shop when I brought it back could not understand how it couldn't work....'its a saucepan, you put on the cooker, there is nothing in it to work' was all they kept saying. She certainly had an antimagnetic personality.

More tragic victims of shiny things.
They aren't sold as "copper nuts" on the MAX site. They might be a new BMW hue–Kardashian Bronze.

I have bought a few sets of these nuts and studs......'copper' is only a coating. Like brass door furniture.....'brass' is often 'brassed' as in coated steel. Always bring a magnet.
